Natural moisturizer products

ABSTRACT

The present invention is drawn to personal care products containing combinations of plant-based glyceride butters and plant-based glyceride oils, and their use in retaining moisture and natural flora in the skin, such as the hands and vaginal lips.

FIELD OF THE INVENTION

This invention relates to personal care products. More specifically,this invention relates to personal care products for use by women,especially those experiencing hormonal fluctuations or decline. Hormonalfluctuations or decline can be related to, for example, birth control,hormone therapy, menstruation, medications usage, childbirth, cancertreatment, polycystic ovary syndrome, perimenopause or menopause. Thepersonal care products of the invention are for moisturizing skin andother body tissues, such as the hands or labia. In embodiments, thepersonal care products maintain and restore the tissue and skin'snatural flora, moisturize the tissue and skin, and can provide soothing,topical relief and relaxation to tissue and skin.

BACKGROUND

Women's bodies undergo a myriad of changes through time, from puberty tochildbearing years to post-menopause. Hormones in the body fluctuateduring these time periods. Although hormonal changes occur throughoutlife, women experience the greatest hormonal changes duringperimenopause and menopause. When a woman misses her period for 12months consecutively, she has reached menopause. Perimenopause(menopausal transition) is the time period before a woman reachesmenopause during which the female body is undergoing a transition inhormone production, and other biological functions related tochildbearing and loss of fertility. Perimenopause can begin shortlyafter the prime childbearing years and occurs at a different age foreach individual woman. While for most women, perimenopause begins in the40s, for some, it can happen as early as the late 30s. The average agefor women to reach menopause is about 52. Therefore, for some women,perimenopause can last 10 or more years. While many women are familiarwith menopause and the biological changes that ensue, most have verylittle awareness of perimenopause and the changes associated withperimenopause. There is, thus, a continuing need for products thataddress biological changes of women that occur around and during thissignificant transition period.

During perimenopause, the production of estrogen, testosterone, andprogesterone changes. As a result, women may experience symptoms suchas: irregular periods, hot flashes, insomnia, night sweats, sleepirregularity, mood changes, vaginal dryness, vaginal pain, urinaryurgency, discomfort during sex, fatigue, breast tenderness, low sexdrive, and loss of bone density. However, not all women experience allthe symptoms to the same degree.

A common problem occurring during perimenopause is tissue dryness. Thisdryness can occur in skin on any part of the body. However, drynessduring perimenopause is a particular problem in delicate and sensitivetissues such as the breasts, the vulva, the vagina, the lips, and theface.

A particular underappreciated symptom of perimenopause is vulvaldryness. The vulval includes the vaginal lips (labia majora and labiaminora), clitoris, vulval vestibule, urinary meatus, vestibular glands,and the opening to the vagina. Vulval skin is more sensitive than skinon other parts of the body because it is much thinner Duringperimenopause, women often experience vulval dryness, which causessymptoms such as itching, pain, rawness, and painful sex. Althoughcommonly known to occur during menopause, many women are unaware thatthese are common problems prior to the onset of menopause, i.e. duringperimenopause.

Another problem that frequently occurs in perimenopause and menopause isthe onset of genitourinary syndrome and vaginal atrophy. Genitourinarysyndrome, which relates to urgency, dysuria, and recurrent urinary tractinfections, is associated with perimenopause and menopause. Vaginalatrophy (also known as atrophic vaginitis, vulvovaginal atrophy, orurogenital atrophy) is an inflammation of the vagina due to the thinningand shrinking of vaginal tissues, and decreased lubrication. Leftunaddressed, vaginal atrophy can lead to pain and discomfort, includingvaginal dryness, burning, and discharge; genital itching; burning orurgency with urination; discomfort during and light bleeding afterintercourse; decreased vaginal lubrication during sexual activity;shortening and tightening of the vaginal canal; pelvic floor muscleseizure; and atrophy closure of the vagina including scarring andprolapse of an organ through the vagina. Sexual activity is essential toproper exercise, endogenous hormone maintenance, and maintenance of thevaginal track. When left untreated, vaginal dryness can result inpainful micro-abrasions along the entire membrane of the vagina,shrinkage, scarring and closure.

Another specific problem during hormonal fluctuation is breast drynessor tenderness, also known as mastalgia. This can result in discomfort innormal daily activities, including disruption of normal movement,concentration, sleep, and intimacy.

Other specific problems associated with hormonal fluctuation are fatigueand/or lack of sleep. When the ovaries stop producing hormones atsignificant levels, the adrenal glands attempt to compensate. However,the adrenal glands only produce a small fraction of hormone that theovaries produced prior to perimenopause and menopause. This reduction ofhormone leads to fatigue. Exacerbating this problem is an adrenalresponse to the increased stress which fatigue can cause, where theadrenal glands consistently produce a rapid and large increase incortisol. These cortisol spikes often occur in the middle of the night,interrupting sleep and preventing women from getting back to sleep. Thiscondition of sleep interruption typically worsens over time if leftunaddressed. Other associated symptoms may include confusion, increasedmoodiness, or mood changes.

Another generalized problem with hormonal fluctuation an increase inchemical hypersensitivity which accompanies dramatic hormonal decline.When the skin (in particular sensitive areas of the skin like thevaginal, vulva, labia, breasts, nipples, face, or lips) comes intocontact with a cream or paste based product that contains syntheticchemicals, women experiencing perimenopause have a high potential tofeel skin irritation, fatigue, and pain.

To alleviate some of the symptoms of hormonal fluctuation, women havebeen prescribed low-dose birth control pills to address the change ofhormones in their bodies. Others have also used birth control skinpatches, vaginal rings, and progesterone injections as hormonetreatments. While replacement hormone therapy may alleviate somesymptoms, such as hot flashes, sweats, and mood changes, it is lesseffective in treating dryness, such as skin dryness, breast dryness,vaginal dryness, and vulval dryness, as well as the concomitant resultsof dryness, including skin discomfort, breast sensitization, vaginalpain, and discomfort during sex. Women have also used personallubricants, body lotions, and petroleum jelly-based products to easesome of these discomforts. However, neither topical hormone therapy noruse of chemical-laden moisturizer gels provides relief of the mostbothersome symptoms of women over a 3-month period.

Unfortunately, alternatives such as personal lubricants, includingwater-based, synthetic oil-based, or silicone-based lubricants areundesirable because they contain synthetic chemicals, includingpreservatives and stabilizers. Thus, heightened chemical sensitivity inperimenopausal and menopausal women makes the use of chemical-basedlubricants detrimental. Additionally, water and alcohol-based lubricantsdehydrate the skin with medium- and long-term use, much like bathwatershrivels the skin on one's hands due to the concentration gradientacross the skin membrane that pulls intracellular fluids out of theskin. Existing personal lubricants and moisturizers were designed toenhance the male experience with short term lack of friction duringsexual activities, but in fact deteriorate the skin and mucous membraneof women. In a clinical trial by Mitchell et al. (JAMA Intern Med. 2018May 1; 178(5):681-690), it was shown that neither a chemical-basedmoisturizer gel nor a topical vaginal hormone therapy were effective inimproving symptoms over a 3 month period.

In their quest for natural product based solutions to these universalproblems caused by normal aging of the female body, now representing ademographic of nearly half of all women, perimenopausal and menopausalwomen have attempted to use food type products, such as coconut oil ormeat lard, as lubricants. The issue with the use of these products,besides not being produced under good manufacturing practices or beingcontaminant and pathogen tested, is that they do not promote a healthypH in the vaginal and labial areas. During perimenopause, the vaginaltract goes from acidic to neutral, leading to conditions such asbacterial vaginosis, an infection where harmful bacteria replaces thenormal healthy flora of a women's vaginal tract. In addition to theaccompanying pain, odor and fever, these infections typically becomechronic and marginally responsive to antibiotics. Women and health careproviders often confuse and misdiagnose bacterial vaginosis infectionswith yeast infection, which typically occurs in women in conjunctionwith abnormal blood sugar levels. As a result of the misdiagnoses, womenare being treated for yeast infections instead of bacterial vaginosis.

Therefore, there is a continuing unmet need for products thatspecifically target dryness, in particular dryness in sensitive areas,for women who are experiencing hormonal fluctuation. More importantly,an all-natural product is advantageous for the vulva to retain moisturewhile simultaneously avoiding irritation to the delicate mucous membraneof the vagina. Also, an all-natural product is preferable to bring thepH of a women's vaginal area to a healthy, acidic level such that thenormal vaginal flora may be restored. A product that is free of alcoholand water is also highly desirable Furthermore, a product is needed toproviding soothing, topical relief and relaxation to these sensitiveareas for women experiencing hormonal fluctuations, particularly duringperimenopause and menopause.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The present invention relates to a personal care product for alleviatingskin dryness. In general, the personal care product promotes healthyskin and tissues. The personal care products can be used on anybody partof the body, such as the hands. The invention is particularly beneficialon skin in sensitive areas such as the labia (or vaginal lips),including both the labia majora and labia minora. In particular, thepersonal care product of the present invention is an all-natural productdevoid of any artificial synthetic chemicals or synthetic hormones, andfree of added alcohol or water. Embodiments of the present inventioninclude a personal care product that contains at least 50 wt. % of atleast one plant-based glyceride butter and at least 15 wt. % of at leastone plant-based glyceride oil. The invention utilizes natural substancesthat provide an acidic pH when mixed in an aqueous environment orapplied on the skin. These natural products and their lipophilicity andpH optimizing effect on sensitive skin and mucous membranes of women arenovel and have benefits not achieved by existing products.

As used herein, the term “formulation” refers to the prepared personalcare product and the terms are generally used interchangeably.

As used herein, the term “about” generally refers to the specific value,plus or minus 5% of said value.

As used herein, the term “balm” generally refers to an ointment orpreparation used to heal or soothe the skin, and has a consistencysomewhere between a heavy liquid and a solid. Balms are typically plantoil and wax-based and are thicker than lotions and creams, and do notcontain water.

As used herein, the term “serum” generally refers to a skin care productdesigned to penetrate deeply into the skin to deliver targeted activeingredients that are quickly absorbed. Serums typically have amedium-body liquid consistency with a non-greasy finish.

All percentages refer to weight percent (wt. %) of the component in thefinal product, i.e. the weight of the component as compared to the totalproduct weight, unless stated otherwise. Weight percentages are subjectto precision and rounding and thus, in general, there is somevariability in exact measures of weight percent, as would be readilyrecognized by persons skilled in the art.

As used herein, “plant glycerides” or “plant-based glycerides” refer toa plant extract of fatty acid glycerides that may includemonoglycerides, diglycerides and triglycerides. In diglycerides andtriglycerides, the fatty acids may be the same or different. Typicalplant-based glycerides contain a mixture of glycerides with differentfatty acids. However, the composition of glycerides from a particularplant extracted in a particular way provides a relatively consistentfatty acid content. Specific plant-based glycerides from various sourcesand in various forms are well known in the art.

As used herein, the term “plant-based glyceride butter” refers to asolid plant-based glyceride. As used herein, solid includes materialswith semi-solid and cream-like consistency at room temperature, and thusincludes materials frequently described as “pastes”. Persons skilled inthe art will readily recognize and identify what is meant by the terms“butter” and “paste” in this context, and as used herein the term“butter” includes “pastes” with their normal and accepted meanings.

As used herein, the term “plant-based glyceride oil” refers to a liquidplant-based glyceride. Typically, plant-based glyceride oils have alower viscosity than water. Persons skilled in the art will readilyrecognize and identify what is meant by an “oil” in this context, and asused herein the term has its normal and accepted meaning.

As used herein, when a glyceride butter (or oil) is described ascontaining (or including or comprising) one or more fatty acids, it isto be understood that the fatty acids are not present as free fattyacids, but that the butter (or oil) contains glycerides that arecomposed of the identified fatty acids. Similarly, when glyceride butteror oil is described as containing a mixture of one or more fatty acids,it is to be understood that the mixture of fatty acids are not presentas free fatty acids, but that the butter or oil contains glycerides thatare composed of a mixture of the identified fatty acids. This does notimply that, for example, all triglycerides or a set of triglycerides allcontain the same fatty acid, but that the butter (or oil) containstriglycerides in which at least one of the three fatty acids is thefatty acid recited. Further, there may be triglycerides that do notcontain the specifically recited fatty acid. For example, a plant-basedglyceride butter (or oil) containing stearic acid may includetriglycerides that have 0-3 stearic acid moieties, but at least somecontain at least one stearic acid moiety. Similarly, where theplant-based glyceride butter (or oil) is identified as containing amixture of fatty acids, that mixture of fatty acids may be from a butter(or oil) extracted from a single source, or may be provided by acombination of butters (or oils) extracted from more than one source.

As will be appreciated, because the personal care product of theinvention is non-aqueous, it does not have a readily quantifiable pH.Accordingly, references to pH in the present specification refer to thepH of the product in an aqueous environment. Because the skin containssome water, the pH described can be considered the pH obtained when thepersonal care product of the invention is applied to the skin.

An embodiment of the invention relates to a personal care product thatmay include natural ingredients, such as plant-based glycerides in theform of butters and oils, along with natural pharmaceutical and naturalcosmetic ingredients. The natural pharmaceutical and natural cosmeticingredients include, for example, vitamin E oil, sodium hyaluronate,sucrose cocoate, sea buckthorn powder, cannabinoids such as cannabidiol,and plant extracts containing these ingredients. Other activepharmaceutical or cosmetic ingredients compatible with the personal careproducts of the invention include, for example, melatonin, retinoicacid, vitamin C, collagen, glycolic acid, salicylic acid, squalene,caffeine, and other natural ingredients.

As used herein, the term hyaluronic acid refers not only to the acid,but also to salts such as sodium hyaluronate, and the terms are usedinterchangeably. Unless specified otherwise, sodium hyaluronate can bereplaced with other hyaluronic acid salts such as potassium hyaluronateand the like. In general, hyaluronic acid and hyaluronate salts can beused interchangeably in products and formulations of the invention,unless stated otherwise. Persons skilled in the art will be able toidentify appropriate forms of hyaluronic acid. The hyaluronic acid usedin the present invention can be obtained from a natural source or asynthetic bioidentical hyaluronic acid that is indistinguishable fromnaturally occurring hyaluronic acid.

As used herein and unless identified otherwise or otherwise clear fromcontext, the term “cannabis oil” generally refers to a hemp extractcontaining one or more cannabinoids, as identified herein, orcannabinoids that may be obtained from a hemp extract. The cannabis oilmay contain a particular cannabinoid compound, a class of structurallyrelated cannabinoid compounds, or a range of cannabinoid compounds. Assuch, a cannabis oil may comprise a single compound or a mixture ofcompounds. Cannabis oil can also be a mixture of cannabinoids from anysource. Cannabinoids used in the present invention can be obtained froma natural source or can be a synthetic bioidentical cannabinoid that isindistinguishable from a naturally occurring cannabinoid.

Plant-based glycerides are extracted from plants. Plant-based glyceridescan include a variety of saturated and unsaturated fatty acidsincluding, for example, palmitic acid, stearic acid, linoleic acid,linolenic acid, arachidic acid, oleic acid, and others, esterified ontoglycerol to form the glycerides. The plant-based glycerides are in theform of a butter or (solid at room temperature) or paste (semi-solid orcream-like at room temperature), or an oil (liquid at room temperature).The physical properties depend on the specific composition of theglycerides (mono-, di-, or triglycerides) and the fatty acid compositionof the glycerides. Most plant-based glycerides are triglycerides and,accordingly, the physical properties depend on the fatty acidcomposition. Examples of plant-based glycerides include extracts ofshea, cocoa, kokum, mango, palm, sunflower, argan, borage, walnut,avocado, apricot, and almond, many of which may be in the form of abutter (or paste), or oil. Other plants may be used to obtainplant-based glycerides. These products are well-known and have theirgenerally accepted meaning as understood in the art. In someembodiments, the plant-based glycerides are deodorized.

While the present invention has been described as containing cocoabutter, kokum butter and shea nut butter, it will be appreciated thatone or more of these specific plant-based glyceride butters may bereplaced by a plant-based glyceride butter of different origin, i.e.from a different plant. If a different plant-based glyceride butter isused in place of a single recited butter, it should have similarphysical properties to the butter it replaces; in particular, similarconsistency and behavior, and preferably also contain a similardistribution of fatty acids, to provide properties consistent with theteachings of this specification. If a different mixture of plant-basedglyceride butters is used in place of the recited mixture of butters,the mixture should have similar physical properties to the claimedmixture it replaces; in particular, similar consistency and behavior,and preferably also contain a similar distribution of fatty acids, toprovide properties consistent with the teachings of this specification.

Likewise, while the present invention has been described as containinghigh oleic sunflower seed oil, argan oil, borage oil, and apricot kerneloil, it will be appreciated that one or more of these specificplant-based glyceride oils may be replaced by a plant-based glycerideoil of different origin. If a different plant-based glyceride oil isused in place of a single recited oil, it should have similar physicalproperties to the oil it replaces; in particular, similar consistencyand behavior, and preferably also contain a similar distribution offatty acids, to provide properties consistent with the teachings of thisspecification. If a different mixture of plant-based glyceride oils isused in place of the recited mixture of oils, the mixture should havesimilar physical properties to the claimed mixture it replaces; inparticular, similar consistency and behavior, and preferably alsocontain a similar distribution of fatty acids, to provide propertiesconsistent with the teachings

Hyaluronic acid is a non-sulfated glycosaminoglycan, naturally found inthe body and is the main component of the extra cellular matrix.Hyaluronic acid is found in high levels in the skin, where it isnaturally produced by both fibroblasts and keratinocytes and exists as apolymer of medium molecular weight (600-1,000 kDa). An importantfunction of hyaluronic acid is to hold water in the intercellular matrixof the connective tissue. This water-binding capacity significantlycontributes to the elasticity of the skin, serving as a water reservoir.With aging, the quantity and quality of hyaluronic acid in the skindecreases, leading to skin dryness.

Embodiments of the invention may include hyaluronic acid or itsderivatives. Hyaluronic acid is a skin hydrating agent that can helprestore water to dehydrated skin. When applied according to a method ofthe invention, hyaluronic acid molecules can deliver substantiallyinstant hydration to the skin. As used herein, the term hyaluronic acidrefers not only to the acid, but also to salts such as sodiumhyaluronate. Similarly, unless specified otherwise, sodium hyaluronatecan be replaced with other hyaluronic acid salts such as potassiumhyaluronate and the like. In general, hyaluronic acid and hyaluronatesalts can be used interchangeably in products and formulations of theinvention, unless stated otherwise. Persons skilled in the art will beable to identify appropriate forms of hyaluronic acid.

The hyaluronic acid used in the invention generally has a very lowmolecular weight, e.g. about 100 kDa or less, about 50 kDa or less, orabout 5 kDa. This low molecular weight allows for increased permeationthrough the skin compared to high molecular weight hyaluronic acid. Thehyaluronic acid can rejuvenate the skin by improving its viscoelasticproperties and significantly decreases deep wrinkles. Hyaluronic acid iscommercially available from a number of sources. Embodiments of theinvention include about 0.0005 wt. % to about 0.050 wt. % hyaluronicacid, about 0.001 wt. % to about 0.025 wt. % hyaluronic acid, orpreferably about 0.005 wt. % to about 0.015 wt. % hyaluronic acid. Inanother preferred embodiment, the invention includes about 0.010%hyaluronic acid.

The present invention can promote efficacy in treating symptoms ofvaginal dryness, prevent stenosis when used in combination with adilator, and prevent dryness associated with using an alcohol-based gel.The invention can be used in advance of intercourse, with a dilatorand/or for general vaginal comfort. Clinical trials indicate that womenwho use labial moisturizers benefit from decreased vaginal discomfort,improvements in intercourse comfort and enjoyment, and increased vaginalhealth and well-being.

Cancer of the vulva, vagina, uterine cervix and uterine corpus isroutinely treated with external beam radiation and brachytherapy.Treatment methods often cause short-term inflammation, bleeding,soreness and irritation and long-term vaginal scarring and stenosis(narrowing). In extreme cases, the vaginal wall can fuse together andscar shut. Cancer patients are counselled to utilize a dilator (glass,plastic or rubber) to prevent the vaginal wall from becoming narrowerand shorter. The vaginal tissue also becomes drier and less elastic,particularly if pelvic radiation has damaged the ovaries and inducedmenopause. The benefits of the invention are useful in alleviatingdifficulties associated with pelvic radiation treatments.
